Abstract
The invention discloses a production method of a warm-proof material for maintaining the hollowness of kapok fiber. The production method comprises steps of performing pre-treatment, carding the fiber, combining by acupuncture, combining in a non-contact mode and the like. In the method, subsequent processes such as drafting, twisting, starching and the like are not needed, the process flow is short, the damage to the fiber is small, and the product directly obtained from the fiber can greatly maintain the hollowness of the kapok fiber and can substitute cotton, down feather and cashmere to process ecological warm-proof products.
Description
Technical field
The present invention relates to a kind of heat insulating material formed production method.
Background technology
Bombax cotton degree of hollowness 94 ~ 95%, cell wall as thin as a wafer, closed at both ends forms natural tail gas capsule structure, content of cellulose is 60 ~ 68% in the fiber, and far below cotton (90% ~ 95%), content of lignin is 13 ~ 15%, far above cotton (0 ~ 8.87%), wax content is 1.8%, torsional rigidity height when not breaking; Fiber stage casing diameter 20 ~ 45 μ m, line density is 0.9 ~ 1.2dtex, length 8 ~ 34mm, and performance is widely different between different cultivars.The special construction of bombax cotton, make advantages such as it has gently, softens, floats, insulation, waterproof, antiacid alkali, anti-mite, but in process, will overcome its light specific gravity, easy difficulties such as flyings, fibre length is short, the smooth surface cohesive force is low, the thin incompatibility farm labourer preface mechanism of wall.The technological process of traditional textile process technology is long, big to fiber destruction, require high to aspects such as fibre length, fineness, the obvolvents of curling, people can only use bombax cotton by blending, technology such as interweave, particularly bombax cotton is in processes such as drawing-off, twisting, starching, the ecosystem hollow structure of bombax cotton is crushed, and himself graceful function is difficult to performance.
Summary of the invention
The object of the present invention is to provide a kind of heat insulating material formed production method to the little maintenance bombax cotton degree of hollowness of fiber destruction.
Technical solution of the present invention is:
A kind of heat insulating material formed production method that keeps the bombax cotton degree of hollowness is characterized in that: comprise the following steps:
(1) pre-treatment: kapok is handled through shredding, removal of impurities;
(2) fiber carding:,, carry out the staggered form laying then and be superimposed body by carding with bombax cotton and thermoplasticity low-melting fiber and other mixed with fibers; Described bombax cotton is that following component in percentage by weight is mixed with thermoplasticity low-melting fiber and other mixed with fibers:
Bombax cotton 10 ~ 70%
Thermoplasticity low-melting fiber 3 ~ 8%
Other fiber surpluses;
(3) acupuncture is compound: above-mentioned superimposed body is adopted nonwoven needled processing, form the three-dimensional composite construction of multiple fiber interweaving;
(4) contactless compound: as will to bake processing through the material of acupuncture Combined Processing, 120 ~ 170 ℃ of baking temperatures, 5 ~ 10 minutes time.
When shredding was handled in the step (1), opener feeding roller speed was 4 ~ 5m/ minute, and hired roughneck's speed is 170 ~ 220 rev/mins, and it is 0.25 ~ 0.3mm that shredding is spaced; When shredding is handled, split the DNA releaxed circular DNA border and add wet process synchronously, ambient humidity is remained on more than 70%.
Other fibers described in the step (2) are one or more in doughnut, synthesizing superfine fiber, kapok other natural fabrics in addition.
Described thermoplasticity low-melting fiber is ES fiber, PP fiber or polyethylene kind fiber.
The present invention does not need later process such as drawing-off, twisting, starching, and technological process is short, and is little to fiber destruction, directly obtains goods by fiber, greatly kept the bombax cotton degree of hollowness, the ecological warming product processing of alternative cotton, eider down and cashmere.
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a bombax cotton aspect graph in the product made of the present invention.
React bombax cotton in the product among Fig. 1 and had the form of ecosystem, kept the ecosystem degree of hollowness.
The specific embodiment
A kind of heat insulating material formed production method that keeps the bombax cotton degree of hollowness comprises the following steps:
(1) pre-treatment: kapok is handled through shredding, removal of impurities; When shredding was handled, opener feeding roller speed was 4 ~ 5m/ minute, and hired roughneck's speed is 170 ~ 220 rev/mins, and it is 0.25 ~ 0.3mm that shredding is spaced; When shredding is handled, split the DNA releaxed circular DNA border and add wet process synchronously, ambient humidity is remained on more than 70%.
(2) fiber carding:,, carry out the staggered form laying then and be superimposed body by carding with bombax cotton and thermoplasticity low-melting fiber and other mixed with fibers; Described bombax cotton is that following component in percentage by weight is mixed with thermoplasticity low-melting fiber and other mixed with fibers:
Bombax cotton 10 ~ 70%(example 10%, 45%, 70%)
Thermoplasticity low-melting fiber 3 ~ 8%(example 3%, 5%, 8%)
Other fiber surpluses;
Described other fibers are that in other natural fabrics beyond doughnut, synthesizing superfine fiber (fineness 1D is following), the kapok one or more are (in any in three kinds of the examples or three kinds two or three, adopting two or three o'clock, can be arbitrary proportion between this two or three component).Described thermoplasticity low-melting fiber is ES fiber, PP fiber or polyethylene kind fiber.
(3) acupuncture is compound: above-mentioned superimposed body is adopted nonwoven needled processing, form the three-dimensional composite construction of multiple fiber interweaving;
(4) contactless compound: as will to bake processing through the material of acupuncture Combined Processing, 120 ~ 170 ℃ of baking temperatures (120 ℃, 130 ℃, 140 ℃, 150 ℃, 170 ℃ of examples), 5 ~ 10 minutes time (example 5,7,10 minutes).
